Application filed March 31, 1909. Serial No. 487,069.

To all whom it may concern:

Be it known that I, WILLIAM H. HOOPER, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented an Improvement in Machines for Treating Insoles of Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

The invention to be hereinafter described relates to machines for treating insoles of boots and shoes.

As well known by those skilledin the art it is usual, to provide insoles with a channel lip which is raised or turned up in order that subsequent operations, such as sewing the insole to other. parts, may be properly performed. When the lip is produced by cutting diagonally into the material of the insole around and toward the sole edge, it becomes difficult to turn the lip up from the channel, especially at the toe portion, be cause the perimeter of the lip edge or top is less in length than the base for any given extent of channel lip, so that as one side portion is upturned it will act to pull down or relay the lip on the opposite side. This action will occur on any part of the channel lip where it extends around a curved part of the insole so long as the center ofthe curve is within and between the edges of the sole, and is most pronounced at the toe portion, being especially noticeable where the insole has a pointed toe, i

With these facts in mind the general aim and object of the present invention are to provide a machine by which insoles maybe incised near the edge thereofand in a ,direc tion transverse to the channel lip so that said lip may be readily upturned, all as will hereinafter more fully appear from. the fol lowing descriptionand accompanying drawings of one form of means forcarrying the invention into practical effect. in

position and showing an insole on the table or work support.

In the following description it will be assumed that the insole S to be treated by the present machine has been previously channeled by a cut extending into the sur face of the insole substantially as indicated by the line 8, Fig. 5, and extending toward the sole edge, although as will be obvious the sole may be first incised by the present machine, as will hereinafter be described, and then channeled.

Extending from the column 1 is an arm 2having a bearing 3 for a stud shaft 4 on which is loosely mounted the pulley 5 having an extended hub 6 disposed between the bearing 3 and a collar 7 secured to the stud shaft 4. by suitable means, such as the screw bolt 8. Loosely supported on the hub 6 is the pulley 9.

Thehub 6 of pulley 5 is provided with an eccentric portion 10 on the side of the pulley 5 opposite the pulley 9, said eccentric being embraced by an eccentric strap 11, Figs. 1 and 4t, and connected at 12 with an arm 13 secured to a shaft 14:. The shaft 14 is mounted to oscillate in a bearing 15 formed in the upper portion of the arm 2, and carries a knife actuator 16, the construction being such that upon rotation of pulley 5, which maybe driven from any suitable source of ower, the knife actuator 16 will be moved ack and forth, as indicated by the arrow a, Fig. 1. When it is desired to let the machine remain at rest for any length of time, the driving belt may be moved onto the pulley 9.

The front portion of the upwardly ex tending arm 2 is provided with a bearing or guideway 17 extending diagonally upward, as indicated in Fig. 1, in which is mounted the knife carrying slide 18 provided with a seat 19, Fig. 1, at its lower portion for a knife 20, sald knife 20, Figs. 2 and 5, being held to its seat by a suitable bearing piece 21 and screw 22. The knife carrying slide 18 is held in its bearing or guideway 17 by means of a face plate 28, Figs. 1, 2, 4 and 5, said face plate being secured to the arm 2 by suitable screws 24 and being provided with a slot 25, Fig. 1, for convenient manipulation of an adjusting screw26, Fig. 1, one end of said adjusting screw bearing upon the upper edge of the knife whereby, upon loosening the screw 22,

Cir

-to the lever 4;?) at 56 and to a said adjusting screw 26 may be manipulated to move the knife into desired position, as will be readily understood.

Fivotally connected at 27, Figs. 2, 3 and 5, to the upper end of the knife carrying slide 18 is a member or finger 28 having a pin 29 to which one end of spring 30 is connected, the opposite end of said spring being secured to a fixed arm 31, Fig. 1, and normally tending to move the member or finger 28 into position, as indicated in Figs. 3 and 5, where it may be met by the knife actuator 16 as it is moved in the manner hereinbefore described.

The knife carrying slide 18 is normally held in retracted position, that is, in raised position, by means of a spring 32, Fig. 1, said spring having one end secured to a fixed part of the framework at 33 and its other end connected to a pin 34 projecting from the knife carrying slide, Fig. 1. In order to limit the upward movement of the knife under the influence of its retracting spring 32, the face plate 23 is provided with a slot 35, Fig. 1, into which projects a pin 36 secured to the knife carrying slide, whereby, when said slide is retracted by its spring 32,

the pin 36 will meet one end of the slot 35 i and arrest further upward movement of the knife.

From the construction thus far described it will be noted that upon actuation of the pulley 5 the knife actuator 16 will be moved back and forth, as indicated in Fig. 1, and, if the member r finger 28 is in the path of movement of the knife actuator 16, the knife carrying slide and its knife 20. will be moved diagonally downward, and, as the actuator l retreats, the spring 32 will retract the knife carrying slide and knife in a manner as will be clearlyunderstood.

Projecting from the member or finger 28 is a toe 37, which, as the knife carrying slide 18 retreats in response to its actuating spring 32, meets a dog 38, 2, 3 and 5, pivoted at 39 to an arm 10 projecting from the face plate 23. The dog 38 has a pin 41 projecting therefrom which engages an angular slot 12 in a controller arm 43 pivoted at 1% to a lever 15 fulcrumed at l6 on the fixed arm said pin 41 of the dog 38 being normally under the influence of a spring 4E7, one end of which is connected at &8 to a projection of the controller arm 13 and the other end of which is connected to the pin d1. The end of the lever to is extended into engagement with a recess d9 of collar 50 supported by a sliding rot 51 which is mounted. in a bracket arm dis a-osed above the work support 53, said red 51 having a work engaging portion or head 54. A spring connected ed part of the machine frame tends norma ly to force the rod 51 and the work engaging head to the left, i, or toward the plane of action of the knife 20, but pern its s.

engaging head and rod 51 to be moved to the right, Fig. 4, by the edge of an insole S pushed thereagainst or placed in working position, the extent of movement of said work engaging head ill and rod 51 being regulated by an adjusting screw 57 carried by an interiorly threaded ing 58. In order that the collar 50 may be properly adjusted en its rod 51 it is nected thereto by a screw thread, as indicated in Fig 4-.

From the construction thus far described it will be apir cut that, if the work engaging head 1 rod 51 be moved the action of the s "ing or to the right Fig. l, the lever h) and it :mtrolling arm -l3 will be correspondingly uroved to carry the end of the dog 38 from tlic p0 iior, indicated in Fig. to that indicai'jed in. Fig 3, thereby freeing the member or linger 8 to the d dlilRCl of its spring and causing it to be moved into the path of the knife actuator 16, which by its movement to the right, Fig. 1, will move the knife carrying le downward to perform its cutting acand, as the knife actuator retreats, the e carrying slide will likewise retreat and. if the end of the dog 38 at such time be in position to engage tletoe 37 of the mean her or finger 28, it will cause the said member or finger 28 to be moved back again tr: the position indicated in Fig. so that the knife will make one cut and then be brought to rest. In, order to effect this action of the dog 38, the controlling arm 43 provided with a shoulder or projection 59. which when the member or linger Z8 in position for actuating the knife. as indicated in Fig. 3, projects into the path of the pin 29 carried by said. member or finger, wherelrv the controller arm is moved about its pivot l!- to cause its slot -12 to more relatively to the pin 41 on the dog 38, so that said pin will meet the angular portion of the slot, as indicated in Fig. 5, whereupon the spring 4-7 will move the dog 38 int position to engage the toe 37 of the member or finger 28 as it retreats in response to its spring 32.

In order to support the work or insole for the act-ion of the ineising knife 20, there is adjustably supported on the column 1 a bracket 60, Fig. 4:, said bracket being preferably secured to the column 1 by means of a screw bolt 61 or the like. The outer portion of the bracket (:0 is provided with u bifurcated bearing 62 for a work supporting spindle (53, said work supporting spindle being adjustable by means of a thumb wheel 64 having a screw thread connection with the lower portion of said spindle and engaging a slot or recess (35 in the edge of the table, whereby, upon loosening the screw bolt 66 which normally clamps the work supporting spindle (33 in adjusted position, the thumb wheel (A may be rotated and the work work i supporting spindle G3 raised or lowered as desired, a spring 67 being interposed between the thumb wheel 64 and the bifurcated bearing 62 of the bracket 60.

Secured to the upper portion of the work supporting spindle 63 is the table or work support 53 having a supporting surface for the insole S which is to be treated and being provided with the rearwardly projecting bearing 52 for the spindle 51, heretofore described. Extending downward from the table is a pin 68 adapted to engage a recess in the bracket 60 to properly hold the table from turning movement. From this construction it will be noted that, as the table or work support 53 is adjusted to suit the character of work, the work engaging head 54 and spindle 51 are likewise adjusted, the collar 50 remaining in engagement with the end of the lever 45 by reason of its slot 49.

In order to position the insole S properly with respect to the knife 20, so that thesaid knife will make an incision into the insole in a direction transverse to the channel lip at the toe, as indicated in Fig. 5, the work engaging head 54 is provided with an indicator or gage 69 preferably formed by beveling the front face of the work engaging head 54, as indicated in Figs. 2 and 5, the median line 69 of the bevels defining the position for the central line of the insole at the toe.

As hereinbefore indicated, it will be apparent that the knife 20 will form an incision not only transversely of the channel lip at the toe but that such incision Will be in an oblique direction through the channel lip, so that when the channel lip is turned upward there will be no flaring opening extending from the top to the base of the channel lip through which the channel guide may pass, but that the diagonal cut will cause the cut portion of the channel lip to overlap and form a continuous guide. It is desirable, also, that the operator may know how far the incision extends transversely of the insole, and as a means of determining this the face plate 23 has its lower portion 70 formed parallel with the surface of the table or work support and its extreme end 71 extended beyond the guide or gage 69 a distance indicating the travel of the knife transversely of the sole. It will be apparent from this that the end portion 71 of the face plate will indicate the end of the incision made by the knife 20. 7

From the construction thus described, the parts being in position as indicated in Fig. 2, if a portion of an insole S, the toe for instance, be moved onto the work support 53 and pressed against the head 54 of the rod 51, the said rod will be moved back and the lever 45 will actuate the controller arm 43 to move the dog 38 from the toe 37 of the finger 28, thereby freeing the finger to movement under the action of the spring 30 and placing the end of the finger in the path of the moving knife actuator 16. As the knife carrying slide moves downward in a direction oblique to the surface of the sole, the knife will form an incision extending into the sole diagonally, as will be apparent. As the knife actuator moves the finger 28 downward, the pin 29 on the finger contacts with the projection 59 on the controller arm, thereby moving the controller arms so that the pin 41 on the dog 38 occupies a position in the angular portion of the slot 42, to the left Fig. 2, or as indicated in Fig. 5, and the dog 38 is then free to move in response to its spring 47, thereby moving the end of the dog 38 in position, as indicated in Fig. 5, so that on the upward movement of the knife carrying slide the toe 37 will meet the dog and throw the finger 28 outward from beneath the knife actuator 16, as will be understood.

From the above it will be noted that, regardless of whether the operator removes the sole from its position in the machine or not, the knife will make one cut and then come to rest in its initial position.
